Step-by-step explanation:

x = number of minutes

the cost function (in c) of the phone company is

cp(x) = 12x

and the cost function of the discount company is

cd(x) = x/2 + 4600 (R46)

we now need to calculate for what x this becomes the same cost :

12x = x/2 + 4600

24x = x + 9200

23x = 9200

x = 400 minutes

she would have to talk for at least 400 minutes long distance per month to make it an even or then better deal.

with 400 minutes being the break-even point.

so, to make it a better deal (not just equal), she has to talk for at least 401 minutes per month.

Inconclusive

Step-by-step explanation:

aₙ = (-1)ⁿ / (n + 6)

aₙ₊₁ = (-1)ⁿ⁺¹ / (n + 1 + 6)

lim(n→∞)│aₙ₊₁ / aₙ│

lim(n→∞)│[(-1)ⁿ⁺¹ / (n + 1 + 6)] / [(-1)ⁿ / (n + 6)]│

lim(n→∞)│[(-1)ⁿ⁺¹ / (n + 7)] × [(n + 6) / (-1)ⁿ]│

lim(n→∞)│[(-1)ⁿ⁺¹ / (-1)ⁿ] × [(n + 6) / (n + 7)]│

lim(n→∞)│-1 × [(n + 6) / (n + 7)]│

lim(n→∞) [(n + 6) / (n + 7)]

1

The limit equals 1, so the ratio test is inconclusive.

The statement is false.

Answer:

○ -1

Step-by-step explanation:

Looking closely at this piecewise function, when the line on the left-hand side intersects at -3 = y, x is -1.

i hope this work for you

Answer:

The pattern goes by adding -3.

Using the arithmetic sequence, you can find the 22nd term.

[tex]t_{22} = -2+(22-1)(-3)\\t_{22} = -2+21*-3\\t_{22} = -2-63\\t_{22} = -65[/tex]

Answer:

  8

Step-by-step explanation:

The distance can be found by subtracting the left number from the right number:

  (3 3/8) -(-4 5/8) = (3 3/8) +(4 5/8)

  = (3 +4) +(3/8 +5/8) = 7 + 8/8

  = 8

The distance between the points is 8 units.

15 is the value of the missing side of the right-angled triangle.

An isosceles triangle, which consists of a pair of sides as well as sides with angles identically, is additionally recognized as a right triangle. Two 45° angles and a 90° angle make up a right isosceles triangle. The triangle's three sides add up to 180 degrees in total.

The information that is provided is with respect to the right triangle:

Side 1 is given as = 9

Side 1 is given as = 12

Applying the Pythagoras theorem:

[tex]H^{2} = S1^{2} + S2^{2} \\= 9^{2} + 12^{2} \\\\= 81 + 144\\=225\\h = \sqrt{225} \\h = 15[/tex]

Answer:

12

Step-by-step explanation:

(10x - 20) + (6x + 8) = 180

16x - 12 = 180

16x = 192

x= 12

Hi there!

This is an example of supplementary angles, angles that sum up to 180° (they form a straight line).

Summing these two angles up equals 180°, so:

180° = (10x - 20)° + (6x + 8)°

We can drop the ° sign for ease of solving.

180 = 10x - 20 + 6x + 8

Combine like terms:

180 = (10x + 6x) - (20 + 8)

180 = 16x - 12

Add 12 to both sides:

192 = 16x

Divide both sides by 16:

192/16 = 16x/16

x = 12°
